并联混合动力汽车模糊控制能量管理策略研究

针对一款并联混合动力汽车,以提高整车燃油性和改善尾气排放为控制目标进行了能量管理策略研究。将混合动力系统整车需求转矩与当前转速下的发动机最优转矩差值（ΔT）、电池组荷电状态（SOC）作为模糊转矩控制器输入,发动机输出转矩作为控制器输出,设计了25条控制规则,基于ADVISOR仿真验证该策略的有效性和可行性。仿真研究表明,提出的能量管理策略提高了发动机工作效率,减少了燃油消耗和尾气排放,并能维持电池组的SOC在合理的范围内波动。

Fuzzy Control Strategy of Parallel Hybrid Electric Vehicle Energy Management

To improve fuel economy and emission,the energy management strategy of parallel hybrid electric vehicle was researched.A fuzzy torque controller with 25 rules was designed using the difference value of the demand torque of hybrid drive system and the engine optimal torque value with current speed and the battery state of charge（SOC） as the inputs,and the engine output torque as the output.The efficiency and feasibility of the proposed control strategy was tested under ADVISOR.Simulation results show that the proposed energy management strategy improved the engine work efficiency,reduced fuel consumption and emissions,and maintained the SOC of battery in a reasonable range.
